These jerky chicken dog treats are my dog’s absolute favorite! I love that it is high protein so I feel he is getting something healthy. Very generous size, and love that they don’t smell. I have a large German Shepherd and he chomps these up with no problem. They are a good value for the money and I have ordered them many times
